CARDlNG-MAOHINE.

SPECIFICATION forming part of Letters Patent No. 759,439, dated May 10, 1904.

Application filed November 13, 1908. Serial No. 181,026. (No model.)

To (Ll/Z when it may concern: 7

Be it known that 1, JOHN J. I'IENDERSON, a citizen of the United States, residing at Oordaville, in the county of Worcester and State of Massachusetts, haveinvented anew and useful carding-Machine, of which the following is a specification.

This invention relates'to that class of machines which are employed for carding or straightening the fibers of wool, cotton, or other textile materials.

The especial objects of this invention are to provide an arrangement of rolls cooperating with the main cylinder of a carding-engine by means of which the stock may be acted upon repeatedly by the same worker, to arrange the rolls cooperating with the main cylinder of a carding-engine in such a manner that a greater number of rolls may be employed without increasing the size of the main cylinder, and to provide a simple and eflicient arrangement of belting for driving the rolls at proper speeds.

To these ends this invention consistsof the improvements in carding-machines as hereinafter described, and more particularly pointed out in the claims at the end of this specification.

In the accompanying drawings, Figure 1 is a sectional view of sufficient parts of a carding-machine to illustrate the application of my invention thereto, and Fig. 2 is a fragmentary view showing in diagram the path of the stock with respect to one set of rolls cooperating with the main cylinder.

In that class of machines to which this invention relates a number of workers are arrangedto cooperate with a main cylinder, the workers acting successively on the stock to straighten or comb out the fibers thereof, the stock which is taken off upon each worker being restored to the main "cylinder by a stripper.

In the ordinary form of carding-machines the arrangement of parts is such that only six workers can be arranged around the portion of the periphery of the main cylinder which is available for use.

One especial object of my present invention is to provide a construction in which a larger number of workers may be set in position to cooperate with the main cylinder without increasing the amount of surface of main cylinder utilized.

In the construction I have herein illustrated eight workers are arranged to cooperate with the main cylinder, whereas in prior constructions the maximum number of workers, as hereinbefore stated, has not exceeded six.

In the ordinary form of carding machinery, furthermore, the strippers are set in advance of the workers, so that the stock in one passage through the machine will be acted upon only once by any particular worker.

In a carding-machine embodying this invention I prefer to arrange the strippers at the rear of the workers, so as to obtain a repeated carding action from each worker ifthe same be required to straighten and card the fibers of stock.

Referring to the accompanying drawings and in detail, the carding-machine herein illustrated comprises the feeding-in rolls 10, from which stock is taken by an intermediate 11 and carried to a licker-in 12. From the licker-in 12 the stock is taken onto the main cylinder C. At the out-feed side of the main cylinder the stock is raised by a long-toothed fancy 13, and the stock is taken off from the main cyl inder by the dofi'er 1 1. Cooperating with the main cylinder O are a plurality of sets of rolls. As illustrated, each of these sets of rolls in' cludes a worker 15, turning in the opposite direction from the main cylinder at a comparatively slow speed. From the worker 15 the stock is taken by atransfer-roll 16, turning in the opposite direction from the main cylinder and at a higher peripheral speed than the Worker 15 and is carried onto the worker 17, which turns in the same direction as the main cylinder and at higher speed than the.

worker 15. From the worker 17 stock is taken off by a stripper 18 and put back onto the main cylinder. The passage of stock through a set of rolls as thus arranged is illustrated most clearly in Fig. 2. As shown in this figure, it will be seen that the stock is taken by the worker 15 from one point on the main cylinder, passes substantially around the worker 15, thence over the transfer-roll 16 and under the worker 17 while at the same time stock is being taken from the main cylinder by worker 17 and added to the stock which has already been loaded thereon from the worker 15, both layerspf stock being returned to the main cylinder by the stripper 18. In this operation a portion of the surface of the worker 17 will have a double quantity of stock thereon; but I have found in practice that the worker 17 can readily carry a double quantity upon aportion of its periphery without overloading.

The rolls of a carding-machine constructed according to this invention may be driven at proper speeds by any convenient connections.

As herein illustrated, I may provide a single driving-belt B, which is driven from the shaft of the dolfer and passes over intermediate pulleys 19. Between each pair of intermediate pulleys 19 a loop of the driving-belt B passes around pulleys to drive the two workers and transfer-roll of a set of rolls cooperating with the main cylinder. The strippers may be driven in any usual manner-as, for example, by being belted at the opposite side of the machine from the fancywhich is the usual practice in the use of machines of this kind.

In the operation of a complete carding-machine constructed according to this invention it will be seen that the stock may be acted upon repeatedly by the same worker in a single passage through the machine if such action is necessary to straighten or card the fibers thereofthat is to say, in a machine constructed according to this invention I preferably arrange the parts so that repeated carding action will be secured.

I am aware that numerous changes may be made in practicing my invention by those who are skilled in the art without departing from the scope thereof as expressed in the claims. I do not wish, therefore, to be limited to the particular construction I have herein shown and described; but

What I do claim, and desire to secure by Letters Patent of the United States, is

1. In a carding-machine, the combination of a main cylinder, and a plurality of sets of rolls cooperating therewith, each set including two workers, said workers each engaging the main cylinder, but which are not in engagement with each other, a transfer-roll for transferring the stock from one worker onto the other, and a stripper for taking stock from the last-named worker and replacing it on the main cylinder in position so that the stock will be repeatedly acted upon by said workers.

2. In acarding-machine, the combination of a main cylinder, a plurality of sets of rolls cooperating therewith, each set comprising two workers having clearance between them, but each of which engages the main cylinder, ar transfer-roll for transferring stock from one worker to the other, and a stripper for returning stock to the main cylinder in position to again be operated upon by the workers, the second one of the workers turning at slow speed and in opposite direction from the main cylinder, the transfer-roll turning in the opposite direction to the main cylinder and at higher peripheral speed than the second worker, the first worker turning in the same direction as the main cylinder and at an increased speed over the transfer-roll, and the stripper turning in the opposite direction to the main cylinder at increased speed over the first worker,and a single driving-belt for turning said rolls.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
